What is Carprofen for dogs?

Carprofen for dogs goes by many names. The brand name Rimadyl is the most common. It belongs to a group of drugs called non-steroidal anti-inflammatory drugs (NSAID). Other examples of NSAIDs are aspirin and ibuprofen.

Carprofen is typically for dogs and cats, so you’ll need to get a vet’s recommendation before using it.

What is it used for?

Carprofen is commonly known for treating conditions related to pain and inflammation, such as Osteoarthritis. In some cases, it promotes healthy bones and prevents abnormal metabolism.

You can give it to various animals, including dogs, cats, birds, reptiles, and small mammals, but you should only do so under a vet’s guidance, as getting the right dosage is very important.

Is it safe?

When used short term and at the correct dosages, this drug is relatively safe for dogs. As with all NSAIDs, there is a very real risk of Kidney impairment when used long term

According to Pet Poison Helpline, Carprofen only has a mild toxicity level. When given in proper dosages, it’s safe, but serving too much of it could be risky.

Dogs who eat toxic amounts of Carprofen could experience:

  • Vomiting
  • Diarrhea
  • Black, tar-like stool
  • Lethargy
  • Accidental urination
  • Excessive thirst
  • Abdominal pain
  • Seizures

If your furry friend suffers from any of the above symptoms after consuming too much Carprofen, contact your vet immediately.

Carprofen dosage for dogs

Giving your dog the lowest dose of Carprofen for the shortest duration is recommended to keep them healthy and safe. When your vet prescribes Carprofen, they will provide directions with the prescription.

The recommended dosage for dogs is approximately 2 milligrams per pound of body weight. You can split the dosage into two servings of 1 mg/lb each day, or you can serve it all at once.

Carprofen side effects in dogs

There are many potential side effects of Carprofen for dogs. Never give your dog more than their recommended dosage. If you forget to feed them with their dose one day, give it to them as soon as you remember. However, if you remember it too close to their next scheduled dose, skip the one they missed.

Some potential side effects include:

  • Gastrointestinal upset
  • Liver, kidney, or gastrointestinal damage
  • Disorientation
  • Behavioral issues
  • Paralysis
  • Seizures

If your dog is suffering from one of these side effects, you might notice some unusual symptoms. They might experience vomiting, diarrhea, constipation, lack of appetite, lack of energy, bloody stool, increased drinking and urination, or yellow skin.

Carprofen could also interfere with lab results, including blood cell counts, thyroid levels, potassium levels, kidney values, and liver enzymes. If your dog displays unusual behavior after taking Carprofen, visit your vet right away.


Carprofen’s cost for dogs greatly varies based on the tablets’ milligrams, where you buy them from, and how many tablets you order. Depending on your dog’s weight, you may have to give them multiple pills daily or cut pills in half. Most carprofen tablets come in 25 milligrams, 75 milligrams, or 100 milligrams.

A single 25-milligram tablet of Carprofen ranges from $0.25 to about $1.07. One 75-milligram tablet can range from $0.31 to $1.32. Finally, a 100-milligram tablet will cost you $0.40 to $1.63.

Most dog parents will buy 30 to 60 pills at once, depending on their dog’s needs. So, you can expect to pay anywhere from $10 to $90 for a bottle. If you have a larger dog, you may need a larger amount at once.

Drug interactions to be aware of

It’s best if you’re always careful when giving your dog two medications at once. If your dog already takes a prescription before using Carprofen, consult your vet to ensure the two are safe to take simultaneously.

These medications should be used with caution if given with Carprofen:

  • Anticoagulants
  • ACE inhibitors
  • Aspirin and other NSAIDs
  • Corticosteroids
  • Cyclosporine and other nephrotoxic medications
  • Insulin
  • Oral antidiabetics
  • Loop diuretics
  • Methotrexate
  • Tricyclic antidepressants

Since there are so many potential drug interactions, you should always inform your vet of new drugs your dog is taking. Otherwise, taking two medications at the same time could cause additional or increased side effects.

Natural alternatives

If you’re uneasy about giving your dog Carprofen for health concerns, why not try a natural option? In a recent study, dogs with Osteoarthritis were given CBD oil twice a day. After two weeks, the dogs showed improved mobility and less visible discomfort.
